White Pheasant Production: Evaluation of Brooding Space, Phase Feeding Method and Carcass Composition
نویسندگان
چکیده
Two experiments were conducted during a growout of male and female white pheasants to evaluate brooding space needed the first 6 wk and appropriate phase feeding strategies in the growing-finishing stages of growth. One-day-old chicks were placed into brooder pens with stocking rates of 150, 200 or 250 chicks/pen. Individual body weight and feed conversions for each pen were measured at 3 and 6 wk of age and litter moisture was measured at 3 wk. Birds were separated by gender at 6 wk and fed a common grower diet to 12 wk of age. At 12 wk, approximately half of the birds of each gender were fed either the grower diet or a finisher diet containing about 5 percentage units less crude protein than the grower diet. Body weight and feed conversion were measured on a pen basis at 12 wk for all birds, 17 wk for cockerels and 20 wk for hens. At market age, a sample of birds from each pen was selected to measure carcass yield and proximate analysis. There were no effects on body weight, coefficient of variation of body weight within pen, or feed conversion in the brooding period. High stocking density (250 chicks/pen) increased litter moisture at 3 wk. There were no dietary treatment effects on growth performance or carcass traits for either gender in the growing-finishing phases. The results showed that dietary protein could be reduced by 23% in a finisher diet fed after 12 wk of age to white pheasants.

The main aim of the present work was to find out whether intensive fattening of pheasant poults can provide high-quality pheasant meat. The study is a pilot work in this area because until now pheasant rearing has only produced pheasants for the purpose of hunting. In this experiment three feeding mixtures were designed; nutritional and energetic composition of the mixtures complied with the re...

Little scientific information is available that has evaluated safflower (Carthamus tinctorius) cake as a substitute to conventional ingredients in small ruminants diet. The objective of this work was to evaluate the effect of feeding safflower cake in total mixed rations (TMRs) on lamb and kid growth rates, carcass traits and meat fatty acid composition. Two consecutive trials were conducted us...

The effect of carcass weight, age at slaughter and sex on some chemical components was evaluated in twenty-two Boutsiko lambs (twelve females and ten males). Chemical composition of meat was expressed as percentage of fat, protein, collagen and moisture content. Measures of the four chemical components were taken by carcass cuts included shoulder, leg, racks, kidney, rear flank, breast ribs and...
